“…All compounds increased until 9 days after the start of the incubation period, and then further increased slightly or stayed constant from 9 to 15 days. Narita et al examined the production of ZEN, α-ZEL, and β-ZEL during incubation of F. graminearum on potato dextrose agar medium 24) , and reported that the production profiles of α-ZEL and β-ZEL were similar to that of ZEN with three of the four strains tested, but a different production profile was observed with the other strain. Our results also indicated that the production of the 5 ZRCs increased in a manner similar to ZEN.…”

We incubated Fusarium semitectum on sorghum and measured the production of zearalenone (ZEN) and ZEN-related compounds (zearalanone (ZAN), α-zearalenol (α-ZEL), β-zearalenol (β-ZEL), α-zearalanol (α-ZAL) and β-zearalanol (β-ZAL)) in the culture by LC-MS. Of the five ZEN-related compounds, ZAN and β-ZEL were mainly detected. The concentrations of ZEN and the five ZEN-related compounds increased until 9 days after incubation and then increased slightly or stayed constant between days 9 and 15. The ratios of α-ZEL, β-ZEL, α-ZAL and β-ZAL to ZEN decreased in a similar manner after 7 days, whereas the ratio of ZAN to ZEN remained constant after 5 days. Analysis of naturally contaminated sorghum by LC-MS/MS revealed that the production ratio of α-ZEL to ZEN was inconsistent with that of our in vitro incubation analysis. The results indicate that ZAN might not be suitable for use as an internal standard.
